board blank from which the able to form a distended interior wall structure ofa receptacle made from said blank. 1 r s 1 The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed. 1 1

In the accompanying drawings, forming part of this disclosure, is illustrated one form "of embodiment of the invention, in which drawings similar reference characters designate corresponding parts, and in whichz I Figure 1 is a perspective view of a collapsible paper board receptacle made in'accordance with thepresent invention; I I Figure 2 is an enlarged vertical sectionalview on theline 22 of Figure 1,'looking in the-direction indicated by the arrows;

Figure 6 is a view similar to Figure 5, showing a portion of the wall structure ofthe receptacle I distended therein;

Figure 7 is a view similar to Figure 6, showing the wall'structure further distended'within the Referring to the drawings, particularly to Figure 3, the numeral 8 indicates broadly a paper board blank from which the receptacle is made.

The blank "8 has formed thereon a plurality of triangular panels 9 having score lines l0 therebetween enabling said panelsito be folded one with're'spect to another. One of the panels 9 .of the blank has formed thereon flaps H and I2, there being a score line l3rformed on the blank between that paneland the flaps enablingsaid .flaps to be folded relative to said panel, fl'he naps H and 12, as by application of adhesive thereto indicated at, II, are adapted to headl esivelysecured to the first of the panels., 9 viewed counter-clockwise from said flaps in Fig ure. 3 of the drawings.

The apex ends of the panels 9 have extending transversely thereof, spaced parallel score lines Hi forming on the inner ends of the panels relatively bendable interconnected portions or parts 15in the form of small strips progressively in- -..creasing in length from thecenter of the blank paper board blank havingparts relativelytbend- -'5'5 --ou'twar.dly thereof.

The flap Il has extending lines HI and I3' between said perforations,

transversely thereof spaced parallel score lines l1 forming relatively bendable elements I8 interconnected with each other and with the parts I6 and providing continuations of the latter in the form of small strips progressively increasing in length from the center of the blank outwardly thereof. A V-shaped notch 19 is formed in the blank between the flaps H and I2 and extends inwardly to the score line I3.

The blank 8 has formed therein from the center thereof outwardly along the score lines In and I3, spaced perforations 20 and, as will clearly appear from Figure 3, the score lines l and I! extend transversely of the panels 9 and'the flap II, respectively, to said perforations. The blank 8 is provided at the base or outer ends of the panels 9, with flaps 2| and score lines 22 between said panels and flaps. Also, the blank "8 has formed therein upon the score lines 22 between certain of the panels 9 and flaps 2|, elongated slots 23. The blank 8 is made from a single piece of card or other suitable paper board and may be cut, scored and formed, as shown in Figure'3.

The blank 8 is initially set up by folding the panels 9 relatively and inwardly and bringing the score line [3 into alignment with the free edge of the panel 9 which, as viewed in Figure 3, is disposed at the top of said blank. At the same time, the opposed ends of the scor lines [5 of that panel and the score lines I! of the flap l I are aligned and overlapped, whereupon the flaps I l and I2 are adhesively secured to said panel. The flaps-2l are then folded or bent downwardly from the panels 9 along the score lines 22, thus forming an open collapsible paper board article of inverted pyramidal form such as shown in Figure 5 and indicated broadly at 24 therein.

The score lines l5 and I! will now be disposed in fixed relation, and the relatively bendable interconnected parts [6 and [-8, which are of polygonal form, will provide at the center of the article 24 a wall structure indicated broadly at25. The downwardly folded flaps 2| will, when the article 24 is set up in receptacle form as hereticle 24 therefrom such as shown in Figure 5,

whereupon he will collapse said article into the "fOIIIl shown in Figure 4 and ship the articl to.

the trade in collapsed form for use by the customer.

'In setting up the article 24, th customer or user first opens it into the form thereof shown in Figure 5. Then, by placing the apex end of the article upon the surface 26 of a counter or other solid support, and applying pressure downwardly on the article, as indicated by the downwardly directed arrows in Figures 5, 6 and 7, the wall struc- -ture 25 will be distended upwardly within the article to set it up in receptacle form. In this setting up operation, the perforations 29 provide for-slight displacementof the paper board ma- ,terial located upon those portions of the score This enables the parts I6 and I8 of the wall structure 25 to readily bend relatively and upwardly and progressively enter the article 24, as indicated by the upwardly directed arrows in Figures 6 and 7, when said article is set up in receptacle form in the manner described.

All, or portions only, of the wall structure 25 may be distended within the article 24 to vary the size of the receptacle set up therefrom. Figures 6 and 7, for example, show receptacles of different heights made from the same article. Figure 7 shows, in dotted lines, the wall structure 25 distended within the article 24 to form a receptacle therefrom of another size. Figures 1 and 2 show in perspective and cross-section, respectively, a form of receptacle in which the outermost polygon of thewall structure 25 and which is comvprisedby the outermost endwise connected parts l5 and I8, forms the base of said receptacle. The outermost polygon of the wall structure 25 could, however, also be distended within the receptacle, in which case the base of the receptacle would b formed by the edge between said polygon and the upwardly and outwardly flared portions of the panels 9.

The portions of the panels 9 within which the wall structure 25 is distended, form side walls 21 of the receptacle and, in the form of embodiment of the invention herein disclosed, the wall structure 25, when distended within said side walls, forms a pyramidal shaped bottom wall forsai'd receptacle. The receptacle herein shown is of the basket type primarily for use to contain and display goods of various kinds. In this case, an advertising sign or card, indicated broadly at 29 in Figures 1 and 2, may be employed in conjunction with the receptacle. The card 28 may be scored longitudinally, as at 29, to provide relatively foldable panels 30, and said card has projecting from the bottom thereof, tabs 3! insertable in th slots 23 to removably position the card on the receptacle at the upper edge.

The receptacle having been set up for use as described, may at any time be collapsed and stored away for future use. In this case, th card 28 is removed from the receptacle to be stored away therewith, whereupon the wall structure25 is pressed downwardly and distended to the position shown in Figure 5. Thereupon the open article 24, thus again formed, is collapsed .as shown in Figure 4, for storage of said article'zin any convenient place.

Blanks and collapsible articles or receptacles made therefrom and embodying the present invention and particularly the distensible wall structure thereof, may be made of various shapes, forms and sizes, and while one form of embodiment of said invention has been illustrated and described herein with more or less particularity, it is to be expressly understood that the invention is not limited to said form of embodiment-or otherwise than by the terms of the appended claims.
